ParentModel

ParentModel["parentModel"]

is used in a model file to indicate that the model build directly on top of the parentModel file.

Details and Options

  • ParentModel["parentModel"] must be the first expression (non-comment) in a model file for the syntax to be valid.
  • ParentModel does not valuate to anything. It is used only in model files to indicate that LoadModel should load the parentModel file first.
  • parentModel must specify a valid model file following the ordinary rules for specifying model files in LoadModel.
  • The Lagrangian from the parentModel file is added to the Lagrangian specified in the current/child model file.
  • It is allowed for the parentModel file to point to a file that itself uses ParentModel to chain models together.
  • LoadModel can modify parameters and options from both the current/child file and the parentModel, using the options ModelParameters and SetModelOptions.
  • The following options can be given:
  • "Use Lagrangian" Truespecifies that the parentModel Lagrangian should be added to the Lagrangian specified in the current file.

Basic Examples  (1)

Many simple BSM models, such as the Singlet_Scalar_Extension provided with Matchete, build on top of the Standard Model. The SM can be loaded by using

as the first expression in a model file.

Options  (1)

"Use Lagrangian"  (1)

With "Use Lagrangian" False, the Lagrangian of parent model is not added to the child model; e.g.,

Alternative Lagrangians can therefore be specified, while still retaining the convenience of group and field definitions.
